#3 John Cena
Needless to say, no one has won more matches with a big fight feel to them over the course of their career than John Cena. That success has translated quite well to the Elimination Chamber, with him having won three of the five Chamber matches he has been a part of.
In 2006, Cena achieved the seemingly impossible when he survived the Chamber and walked away with his WWE Championship intact. He wasn't quite as fortunate in 2009, but it took finishers from three different Superstars to put him away that year.
While he failed to capture the WWE Championship inside the Chamber in 2014, he had success in the matchup for back-to-back years in 2010 and 2011. Whether he can repeat the feat on Sunday when he defends the gold against five hungry challengers is uncertain, though.
